All right,
thanks Adam.
Unfortunately, there's still a problem.
I managed to build and run(!) a simple 'hello.ko'.
But, i fail with more complex modules.
Building works, but when loading my module with 'insmod' i get faults:
Page fault (non-resolved): pfa=9 pc=1011cec
Non-resolvable page fault at 9, ip 1011cec.
I'm sure the fault is not caused by my code because there is the same
issue with legacy drivers.
But, i guess something is wrong with the build process.
e.g. let's take CONFIG_TCG_TPM in 'src/l4linux/driver/char/tpm'.
This one does build and run successfully when setting CONFIG_TCG_TPM=m
in 'obj/l4linux/.config' and than building complete l4linux.
But it does not build when going to 'src/l4linux/driver/char/tpm' and
'make -C $L4re/obj/l4linux/arm-mp M=$PWD
CROSS_COMPILE=arm-linux-gnueabihf- L4ARCH=arm CONFIG_TCG_TPM=m modules
V=1'.
It gets me this output:

Sorry, for all the shit.
Hopefully, you see the problem quick.
Guess your more familiar with the build process.
